Draft letter, from Sir John Herschel to Marshall Hall Draft letter, with extensive corrections in Herschel's hand. Returns his packet of papers together with the letters of M. J. P. Flourens, [J. P.?] Müller, etc. Does not feel competent to judge papers such as Marshall Hall's, which lie outside his field of knowledge. Should rid his mind of bias on the part of Council. Submit papers as from himself. 16 October 1839
